Trump ready for greatness - former world champion Ken Doherty

In the other half of the draw, reigning champion Ding Junhui thrashed Robert Milkins 5-1 to set up a semi-final against Stuart Bingham, who beat Ken Doherty 5-3.

Advani - who is an eight-time world billiards champion - set up his last-eight clash against Trump, 23, thanks to a landmark 4-1 victory against Graeme Dott on Thursday.

But he found the going tough against the Englishman, who looked on course for a whitewash as he raced into a 4-0 lead before Advani showed resolve to take the next two fames, including turning around a 59-1 deficit in the sixth.

"Going out early in the last few tournaments means I have had to do a lot of practice on my own, so it is nice to get some match practice," he told BBC Sport Wales. "It is pleasing that my safety is competing well against the top players because my scoring hasn't been that great this week.

"Normally near the end of a frame I go on to clear up but I am nowhere near as confident as I was before Christmas."
